Subject:Adm Msg -- 2003 HUMMER H2 Idler Arm Lubrication (Admin Number HUS20020016 -- 9/25/02)

Models:2003 HUMMER H2

Attention: General Manager, Service Manager, Parts Manager, Warranty Administrator, New Vehicle Manager, Sales Manager


The idler arm requires lubrication at the recommended intervals specified in the Owner's Manual. However, the zerk fitting is apparently not visible and readily accessible. The underbody protection plate on the vehicle (the one embossed with H2) needs to be removed. The idler arm zerk fitting is facing the right hand frame rail of the vehicle. Therefore, a 90 degree fitting on the grease gun is required. The Snap-On part number for the grease gun adapter is YA757.
